Description

This best-seller emphasizes combinatorial ideas—including the pigeon-hole principle, counting techniques, permutations and combinations, Pólya counting, binomial coefficients, inclusion-exclusion principle, generating functions and recurrence relations, combinatortial structures (matchings, designs, graphs), and flows in networks. The Fifth Edition clarifies the exposition throughout and adds a wealth of new exercises.
CourseSmart textbooks do not include any media or print supplements that come packaged with the bound book.
